2025 Senior Deduction Calculator

Estimate the additional Schedule 1-A deduction for one or two eligible people age 65 or older, subject to the MAGI phaseout.

Tax year supported: 2025 only. Reviewed: August 3, 2026.

Schedule 1-A estimate only. The result does not determine age, Social Security number, residency, joint-return, or other eligibility requirements, and it does not calculate tax on Social Security benefits.

2025 Enhanced Senior Deduction

Estimates the additional Schedule 1-A deduction for an eligible taxpayer and, on a joint return, an eligible spouse. It does not calculate the standard deduction or the separate age-based additional standard deduction.

Use the 2025 Schedule 1-A, Part I modified-AGI amount, not taxable income.

Eligible people

A checked person must have been born before January 2, 1961, have a valid Social Security number, and include that number on the return.

How the 2025 estimate works

The starting amount is $6,000 for each entered eligible person. The calculator then reduces that amount according to MAGI and filing status. This deduction reduces taxable income; it is not a credit, payment, or exemption of Social Security benefits.

Frequently asked questions

How much is the 2025 senior deduction?

The maximum is $6,000 for each eligible person age 65 or older, so a joint return may qualify for up to $12,000 when both spouses are eligible. The amount is reduced by the MAGI phaseout.

When does the senior deduction phase out?

The phaseout begins at $75,000 of MAGI for most filing statuses and $150,000 for a joint return. Married filing separately is not eligible for this Schedule 1-A deduction.

Does the senior deduction replace the existing extra standard deduction?

No. The Schedule 1-A senior deduction is separate from the existing additional standard deduction for age or blindness. An eligible person may claim the Schedule 1-A deduction whether using the standard deduction or itemizing, but this tool calculates only the new senior deduction.
